i am going to have to carry out a repair on my tube, (when i bought the rib it had a small scratch on the tube and was assured it did not affect the rib) and after 12 months of searching for a leak i found it,it was the scratch(that was after i had changed the valves).anyway after buying a large piece of hypalon and bostik ne 486,could you guys give me any advice re mixing % of the glue and any other advice as this is going to be my first go at tube repair as i am a tube virgin
many thanks t.
